Seahawk Burger

Ingredients

• 1 teaspoon vegetable oil
• 1 sweet onion (such as Walla Walla), sliced
• 8 ounces mushrooms, sliced
• Salt and ground black pepper to taste
• 1/2 cup Washington state red wine (such as a Merlot or Syrah)
• 4 (6 ounce) grass-fed ground beef patties
• Seattle Aioli:
• 1/2 cup mayonnaise
• 1/2 teaspoon Sriracha sauce
• 1/2 shot brewed espresso (such as Starbucks)
• 4 whole grain or artisan hamburger buns (such as Macrina Bakery)
• 4 slices Monterey Jack cheese (such as Beecher’s Just Jack)
• 1 cup farmer’s market arugula, or more to taste

Directions

Heat oil in a large skillet over medium-high heat. Saute onion and mushrooms in hot oil until onion begins to soften, about 5 minutes. Season vegetable mixture with salt and pepper; continue to saute until onions and mushrooms brown, about 5 minutes more.

Pour the red wine into the pan and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon. Cook and stir until wine evaporates, about 2 minutes; remove from heat.

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Cook burgers until they are firm, hot in the center, and just turning from pink to grey, 8 to 10 minutes per side for medium well. An instant-read thermometer inserted into the center should read 150 degrees F (65 degrees C).

Whisk mayonnaise, Sriracha sauce, and espresso together in a bowl until aioli is smooth.

Spread aioli on each hamburger bun. Place a beef patty on the bottom bun, top with a slice of Monterey Jack cheese, 1/4 the onion-mushroom mixture, 1/4 cup arugula, and cover burger with the top bun. Repeat with remaining burgers.
